Data can exist in alot of different forms but ultimately the data has to be converted into digital form for the computer to process it. When we put data into a structure for processing, such as in a spreadsheet or database, we have to instruct the computer what datatype we are going to use for each item of data.
The key concepts:
Identification of different data types
Selecting appropriate data types for given set of data
Understand the meaning of the terms file and record
Understand the difference between analogue and digital data
Links and more:
To understand data transfer and types, means that you have to understand the meaning of a database. Bitesize have material for this. Start with the Rewise and then do the Activity and test.
